I looked in Red book and even gumtree specs but the numbers are all over the place. 2.92. 308,3.45
If the series 2 sedans use the 2.92 and it appears the utes may use 3.45 a drop down to the 2.92 should gain a good reduction of rpm on the flat. Yes I would need to change back from 6 to 5 on some...
